Product overview and engineering role
The SimtoLink WiFi6 dual-band PCB antenna is a printed radiator on the board, designed together with the product ground, the keep-out, and the RF front end. It fits industrial gateways, enterprise APs, CPEs, and other products that need a built-in dual-band link.
Band, gain, VSWR, and polarization in the table are there to line up with the chip reference design and the match. Laminate and stack-up change the measured pattern. The Hardware Specification and the system EMC report govern.
Reliability and site fit
A metal housing, screws, connectors, and a nearby DDR or switch-mode supply can pull the pattern and the efficiency down through near-field coupling. Leave tuning pads and a reference ground in layout, and repeat radiated-spurious and sensitivity tests on the finished product.
Outdoor or high-humidity builds need a look at how the ingress structure affects the dielectric and the solder joints over time. On a pilot build, SimtoLink recommends a VSWR sample after temperature cycling and vibration.
Key hardware parameters
The table is the typical RF and layout set for this antenna, for selection and for a tender clause. Another laminate, stack-up, or MIMO count is a separate request. Ask SimtoLink for the Hardware Specification and the Installation and Commissioning Guide. Order codes in the family can differ. The nameplate and the documents shipped with the antenna govern.
| Parameter | Specification | Notes |
|---|---|---|
| Band | 2.400～2.4835 GHz; 5.15～5.85 GHz (typical) | Follow the target-market channels and certification |
| Gain | 2～5 dBi | Onboard omnidirectional, typical; changes with the housing |
| VSWR | <2.0 | Typical under the reference layout |
| Polarization | Linear (typical) | MIMO elements set orthogonal |
| Impedance | 50 Ω | Trace to the RF front end |
| Power | Limited by the chip and certified EIRP | Designed with the PA and antenna efficiency |
| Structure | Keep-out plus a continuous ground plane | Bounded by the reference design |
| Interface | Onboard microstrip / spring contact | No external LMR feed |
| Operating temperature | -40～85 ℃ | Depends on laminate and process |
| Mounting | PCB surface-mount / soldered | Keep clearance from the housing |
Typical applications
Four product forms this antenna usually lands in, when you are weighing the scheme and the return:
Industrial gateways and edge boxes
An internal dual-band link for maintenance access and for gathering terminals on site.
Enterprise APs and ceiling units
An onboard antenna cuts stack height and the cost of openings in the housing.
Smart-home hubs
Follows the product industrial design, while keeping MIMO isolation and assembly tolerance in mind.
ODM reference designs
Ships as the RF daughterboard or the module beside it, which shortens certification and the path into volume production.
Installation, grounding, and maintenance
- Keep the keep-out and the no-copper zone. Do not run copper or traces across the main radiator under the antenna.
- Keep the ground reference continuous, and place the via fence as in the reference design, to cut ground bounce and coupling between elements.
- Use HF-stable parts for the match and the balun, and check lot-to-lot consistency before volume build.
- In system EMC, watch harmonics and spurs, and back the power off or add filtering if you need to.
- After a housing-tool change or a laminate change, retest VSWR and the key OTA figures.
Ordering, documents, and support
SimtoLink can issue the hardware specification, outline drawings, a wiring note, and a sample layout. Volume orders can include sample review and inspection at the factory. Warranty and calibration follow the contract and the papers packed with the antenna.
